A neuron ( / ˈ nj ʊər ɒ n / NEWR -on ; also known as a neurone or nerve cell ) is an electrically excitable cell that processes and transmits information by electrical and chemical signaling. Chemical signaling occurs via synapses , specialized connections with other cells. Neurons connect to each other to form neural networks .

Nanowire
A nanowire is a nanostructure, with the diameter of the order of a nanometer (10 −9 meters). Alternatively, nanowires can be defined as structures that have a thickness or diameter constrained to tens of nanometers or less and an unconstrained length. At these scales, quantum mechanical effects are important — which coined the term " quantum wires ". Many different types of nanowires exist, including metallic (e.g., Ni , Pt , Au ), semiconducting (e.g., Si , InP , GaN , etc.), and insulating (e.g., SiO 2 , TiO 2 ). Molecular nanowires are composed of repeating molecular units either organic (e.g.Buckminsterfullerene C 60 (left) and carbon nanotubes (right) are two examples of structures in the fullerene family. A fullerene is any molecule composed entirely of carbon , in the form of a hollow sphere , ellipsoid or tube . Spherical fullerenes are also called buckyballs , and they resemble the balls used in association football .

Microsystem
Microsystem is the name commonly used in Europe to describe the same technology which goes under the name MEMS (Micro Electro Mechanical Systems) in the US. In Japan, this field is often termed micromachines. Microsystems are miniaturized (silicon or polymer) devices which perform non-electronic functions: typically sensing and actuation.
In biology the active site is part of an enzyme where substrates bind and undergo a chemical reaction . [ 1 ] The majority of enzymes are proteins but RNA enzymes called ribozymes also exist.

Wide angle shot of the memory microchip shown in detail below. The microchips have a transparent window, showing the integrated circuit inside. The window allows the memory contents of the chip to be erased, by exposure to strong ultraviolet light in an eraser device.
Integrated circuit
Acoustic metamaterials are artificially fabricated materials designed to control, direct, and manipulate sound in the form of sonic , infrasonic , or ultrasonic waves, as these might occur in gases , liquids , and solids .

Glutamic acid (abbreviated as Glu or E ) is one of the 20-22 proteinogenic amino acids , and its codons are GAA and GAG. It is a non- essential amino acid . The carboxylate anions and salts of glutamic acid are known as glutamates . In neuroscience , glutamate is an important neurotransmitter that plays a key role in long-term potentiation and is important for learning and memory. [ 2 ]

Synthetic resin , an artificial chemical substance which hardens irreversibly, usually a thermosetting plastic or one of the monomeric components thereofAkt , also known as Protein Kinase B (PKB) , is a serine/threonine-specific protein kinase that plays a key role in multiple cellular processes such as glucose metabolism, apoptosis , cell proliferation , transcription and cell migration.
